Section 4: EGP Protocols (17 Points)

Configure BGP, as shown in Figure 1-14, with the following peering:
R3R2, R8R2, R6R2, R6R8, R7R8, R6R5. Ensure
the most suitable interfaces are used to maintain resilience for BGP peering
(except for R2 and R3, use 172.16.0.0/16 addresses for all peering to and from
these routers).
